Application filed May, 1905. Serial No. 259,209.,

e' it knownthat I, CHARLES H. JOHNSON, a

citizen of the United States, residing at'Buffalo, in the county ofErieand State of New York, have invented a new and usefulBottle- Capi, of the following isa specification.

This inventionrelates to bottle-caps.- y i The object of theA inventiorristo provide a novel form of cap whichrnay readily be applied to a bottle and in the use of which intrusion of extraneous matter, such as dustor ine sects, will positively be prevented, while escape of liquid from the bottle will readily be permitted. v

Afurther object is to rovide a bottle-cap having a novel form of c osure which will automatically unseat or open itself when the bottle is tilted for the purpose of pouring out the contained liquid and'which will automatscribed and c aimed.

ically seat or close itself when the bottle is brought again to a vertical position.

With the labove and'other objects in view, as Will appear as the nature ofthe invention is better understood, the sameconsists in the novel construction and combination of parts of a bottle-ca as will be hereinafter fully de- In the accompanying drawings, formin a part of this specification, and' in which li e characters of reference indicate corresponding arts, Figure lis a view in perspective, eX- hibiting a bottle-cap constructed in accordance with the resent invention. Fig. 2 is a view in vertical section through'the neck of a bottle, showing the cap of the present invention combined therewith. Fig. 3 is a perspective detail view of a combined guide and sto employed in connection with the article to lmit the movements of the closure.

The device embodies a collar or bottle-engaging element 1 anda closure or sealing element 2, The collar, as clearly shown in Fig.

' 2, is a cylindrical structure of truncated coneshaped form, may be made of any suitable material, preferably of thin sheet metal, andv has its upper or smaller portion reduced, as at 3, to form a seat, which is engaged by a screen or guard 4, made of reticulated or woven wire a disk 6 and a tubular extension 7, preferably y integral therewith and cleft longitudinally,

as at 8,1 to permit the sections formed thereby to be slightly flexed to present a cone-sha ed '.orifice. Vlorking inthe orifice 9' ofthe isk and the sleeve is a'sternor shank-,10, connected with the upper-end of which is the closure 11,- that is combinedwithl the stem `,inany preferredvmanner and is of a size' to close the .upper end of the collar when seated thereon, as shown in Fig.` 2.` Theloweror inneren-d ofthe `stern or shank is bifurcated, as at 11, the two members formed thereby being outturned, as clearly shown in Fig. 2,' to form abutments or stops 12,l which by engagement with the inner walls of the guide or stop will serve to limit the outward movement of the closure and also to prevent any binding therein. The assemblage of the stem' and the guide is to be such that the former will be free to slide in the latter, so that when the bottle is inverted for the purpose of pouring out the contained liquid the closure will automatically unseat itself and assume. the position shown vin Fig; 1and upon the bottle being restored to its normal or vertical position the closure will automatically seat ltself and lreist upon the upper edge o f the collar, as shown in Fig. 2, thereby effectually sealing ingress to the interior of the receptacle with which the device is used. The guide may be combined with the screen or guard inany referred manner, preferably by having the dered thereto.

sk portion 6 sol-r f In using the 'cap in lconnection with the neck end'N of a bottle the mouth ortion will have applied to it a rubber thimb e.13,which will be of a size to engage closely the innerwalls of the collar, as shown in Fig. 2, and thus hold the latter positively in position thereon, while at the same time permitting ready detachment therefrom.

The cap of the present invention is adapted for various uses, but more particularly in con- IOO close the neck or mouth thereof with a cork.

ing a collar, a screen combined therewith and carrylng a guide, and a closure having a shank movable in the guide.

and a closure having a shank movable in the guide and stop.

4. A device ofthe class described, comprising a collar provided near one end with a seat, a screen secured to the seat, a guide secured centrally to the screen, and a closure having a stem freely movable within the guide.

5. A device ofthe class described, comprising a collar, a screen secured near one end thereof, a guide secured to the screen, and a closure having a shank loosely movable in the guide and Cprovided with means for limiting its outwar movement.

6. A device ofthe class described, comprising. a collar, a screen combined therewith, a disk secured centrally of the screen and llaving an approximately cone-shaped extension, and a closure havinor a stem movable within the disk and provided with terminal abutments to limit the movement of the stem.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two witnesses.

CHARLES H. JOHNSON.
